From ccc7b4c3a17ade90de71e1e0f44deebbffd646e6 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Tue, 26 Mar 2013 23:07:31 -0400 Subject: remove __SYSCALL_SSLEN arch macro in favor of using public _NSIG the issue at hand is that many syscalls require as an argument the kernel-ABI size of sigset_t, intended to allow the kernel to switch to a larger sigset_t in the future. previously, each arch was defining this size in syscall_arch.h, which was redundant with the definition of _NSIG in bits/signal.h. as it's used in some not-quite-portable application code as well, _NSIG is much more likely to be recognized and understood immediately by someone reading the code, and it's also shorter and less cluttered. note that _NSIG is actually 65/129, not 64/128, but the division takes care of throwing away the off-by-one part. --- arch/x86_64/syscall_arch.h | 2 -- 1 file changed, 2 deletions(-) (limited to 'arch/x86_64/syscall_arch.h') diff --git a/arch/x86_64/syscall_arch.h b/arch/x86_64/syscall_arch.h index 1c4b48a2..a85c440c 100644 --- a/arch/x86_64/syscall_arch.h +++ b/arch/x86_64/syscall_arch.h @@ -1,8 +1,6 @@ #define __SYSCALL_LL_E(x) (x) #define __SYSCALL_LL_O(x) (x) -#define __SYSCALL_SSLEN 8 - static __inline long __syscall0(long n) { unsigned long ret; -- cgit v1.2.1
